measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution in the volumetric flask to finally prepare an acidic KHP solution. The molar mass of KHP was calculated and came to be 208.252 grams per mole. To find the moles of KHP‚ the mass of KHP (1.980 g) was divided by the molar mass of KHP ( 208.252 g) and .00951 moles are in the 1.980 grams of KHP. To find the molarity‚ the number of moles of KHP (.00951 moles) was divided by the volume of water in liters

Chemicals in medicines Rakesh Mohan Hallen The words medicine’ and ’drug’ are often used in our country to mean the same substances: any substance‚ manufactured artificially‚ which can help recovery from sickness‚ relieve symptoms or modify a natural process in the body. A medicine is often a mixture of several chemical compounds. Even if it has only one active component compound often other substances are used as fillers or binders to give it bulk. Chemistry‚ the science related to chemical substances

The Ka and Molar Mass of a Monoprotic Weak Acid Chemistry Lab 152 Professor: James Giles November 7‚ 2012 Abstract: The purpose of this experiment was to determine the pKa‚ Ka‚ and molar mass of an unknown acid (#14). The pKa was found to be 3.88‚ the Ka was found to be 1.318 x 10 -4‚ and the molar mass was found to be 171.9 g/mol. Introduction Acids differ considerable as to their strength. The difference between weak and

Experiment 3: Chemical Equilibrium Purpose The purpose of this experiment was to determine the equilibrium constant for the formation of FeSCN2+. Introduction Chemical equilibrium is the point in a reversible reaction where the concentration of the reactants and that of the products remains constant. This point of equilibrium is referred to as the Kc value‚ which can be obtained using the formula: Kc = [product] [reactant] In this experiment‚ we used a spectrophometer to
